The correct use of the hammer:
On July 23, 2011, the rear-end collision occurred. When the passengers were preparing to escape, they found that using a broken window to hammer the glass was invalid, that is, they tried their best to smash the window glass but they did not move, and finally escaped from the cracked part of the carriage.
In fact, the security hammer is not open in the middle of the glass.
What happens when the elevator suddenly falls?
One day, when I took the elevator, I suddenly encountered a sudden power failure. Although the emergency power supply system began to function after a few seconds, the elevator still fell rapidly from the 13th floor. When you face a life-and-death line, every action you make will determine your life and death.
"The best move to protect yourself when the elevator falls." First, (whether several floors) Press the keys on each floor. Second, if there is a handle in the elevator, please hold one hand tightly. Third, the entire back and head are close to the interior wall of the elevator and are in a straight line. Fourth, the knee is in a bent position.
Explanation: Because you don't know when it will land, and when it falls it is likely that you will have a broken body and die. Therefore: The first point is that when the emergency power source starts, the elevator can immediately stop falling. The second point is to fix your position so that you don't fall because of an unstable center of gravity. The third point is to use elevator walls as protection for the spine. The fourth point is that the most important thing is that because the ligament is the only body in the body that is elastic, it uses knee flexion to withstand heavy blow pressure, which is more stressful than bones.
